We have two pond pumps with cartridge type mesh intake filters. These clog frequently, requiring constant cleaning--a real nuisance.
I bought this material, and with common scissors, cut pieces the correct width and length to wrap around the existing (cleaned) filters. Used three wire ties to cinch them up snuggly, and haven't had to clean the filters all year. They don't clog up anymore.

I love the stiffness in this media. I use it to not only filter my pond water, but to hold other media in place. You can see in the picture how I have it wrapped around the other media in the filter box. This was a diy project and it turned out perfectly.

this is a rigid filter media, very easy to handle, cut and rinse. I am using it (cut in to 24") pieces in my biofilter barrels on my 3000 gallon koi pond. this traps particles and muck which facilitates clear water. I also use biological microbes and bio balls. This filter product is superior to the blue one I have previously ordered from a different vendor. That product only lasted me 5 months, I anticipate this one will outlast that. I just installed it one week ago, and will update my review in the future. Very good price, Shipped fast. Simply and adequately packaged. You could also cut this down to use on aquariums and save a lot of money over the little premade filter pads.

Works great. Easy to cut and fit filter. My fish "pond" is only 60 gallons, but it was green and mucky from intense heat wave. This material, with a little barley extract cleaned the pond in about a week. I did have to spray the filter material every two days to remove the trapped algae, but I was amazed at how well it worked.

Works great for my canister filter. The cost is was less than pre-cut ones
